POST CLAMP.

Application filed April 21, 1928. Serial No. 271,890.

My invention relates to devices for joining end to end, wooden post sections such as used tor example in Slfl! )I)Ol'll1lg scattolding.

Hereto'lore it has been customary to nail wooden boards on all sides of the abutting post sections at their junction to unite them. The nails, however, spoiled the boards as well as the posts after much use.

Mv invention consists in its present prefen-ed embodiment of right angle metallic plates to lit and cover the opposite angles oi the abutting post sections, in C()I1]L1I1Cl3l0l1 with a square metallic plate to fit between the abutting ends, said plate being formed with screw holts at its opposite angles to re ceive preferably angular washers and nuts by which the opposite angle irons are clamped tightly on the opposite angles of the post joint and the postsections united securely and easily together.

In order that my invention may be fully rmderstood, I shall first describe in detail the mode in which I at present prefer to carry the invention into practice, and then particularly point out the invention in the claims.

Reference is to be h ad to the accompanying drawings forming part of this application in which like parts are designated by the same numbers in all the figures.

Figure 1 is a side elevation showing two post sections joined by my improved post clamp.

Figure 2 same.

Figures 4, 5, 6. 7, 8, 9, and illustrate he various parts of the said post clamp in detail.

In the drawings, 11 and 12 designate two timber post sections joined end to end by my post clamp.

The post clamp consists of two metallic right angle plates 13, 14, to fit and cover oppositc angles of the post sections at their junction. and having midway diagonal bolt holes 14 at their angles: a square metallic plate 15, preferably a trifle smaller than the section of the post sections, formed at its opposite angles with diagonally projecting screw bolts 16, 17 in the same plane as the plate, and adapted to be placed between the abutting ends of the post sections in correspondence therewith, the opposite screw is an inverted plan View of the bolts 16, 17 being passed through the bolt holes 1% in the opposite angle plates 13, 1d; washers 18 having right angular inner ends 19 to pass over the screw bolts outside the plates 13 and tit the angles of the plates, and nuts 20 to screw on the screw bolts 16, 17, outside the washers.

In using this post clamp, the plate 15 is placed between and in angular correspondence with the abutting ends of the post sections 11 and 12. The angle plates 13 and 1.4: are then fitted against the opposite angles of the post sections at the junction thereof, the threaded bolts 16 and 17 of the plate 15 being passed through the respective bolt holes lat midway of the length of the angle plates 13, 14. The angle washers 18 are then passed over the respective screw bolts 16 and 17, against the respective angle plates 13 and 14, and the nuts 20 screwed on the respective screw bolts 16, 17, tightly against the respective washers 18.

The angle plates are thus clamped tightly against the opposite angles and respective sides of the post sections 13, 14, which are thus rigidly and securely joined together for use.

When no longer needed, the post sections are easily taken apart by unscrewing the nuts 20 and removing the washers, angle plates 13 and 14, and squeeze plate 15, without in any way injuring the post sections.

This post clamp can be used indefinitely for this and analogous purposes.

It is evident that the specific form of my invention here illustrated may be greatly varied without departing from the boundaries of my invention as defined by the follow ing claims.

I claim as my invention:

1. A post clamp comprising a squeeze plate to be placed between the abutting ends of the post sections and having screw bolts projecting oppositely therefrom, and clamping plates to fit against opposite sides of the abutting post sections having bolt holes to receive the said screw bolts, and nuts to screw on the screw bolts, and press the side plates against the abutting post sections.

2. A post clamp in accord with claim 1, in which the screw bolts project from opposite angles of the squeeze plate, and the clamping plates are angled to fit against opposite angles of the abutting post sections and have bolt holes midway at their angles through. which the screw bolts are passed.

3. A post clamp in accord With claim 1 in which the clamping plates are angled to fit against the opposite angles of the abutting post sections; the screw bolts pass through the angles of the clamping plates, and Washers having angle ends to fit the angles of the clamping plates are placed on the screw bolts between the clamping plates and the nuts.

In testimony whereof I affix my signature.

DAVID SALUSTRI.
